Quote from: Petrus on January 5, 2023, 09:08btw Lee, you máy be a bit on the optimistic side with 950 kg. for your FL. It is most likely around 1050 depending on how much fuel you have sloshing about.
Quote from: LeEdFollow on January 5, 2023, 09:47Will certainly take me some time to get that confidence in the Roadster. 99% of all my car history is FR, only MR cars I've owned before the Roadster was a Lotus Esprit HC Turbo and an AW11 which both tried to kill me on many occasions lol
Quote from: Petrus on January 5, 2023, 10:13As to the weight you´ll see. The under 1000 kgs is a combo of dry weight marketing the (JDM) PFL. My PFL (SMT/AC) has 1060 kgs on the registration papers.
Quote from: Petrus on January 5, 2023, 11:47Although the fluids are about correct, it is academic. Only a lowish fuel level is a low as thát gets in the real world My observation was to point out that real world weight of your car is not 950 ks. Weighing will give you a real number and a solid base to measure your gains from.@JB21 gives a great example. He added a lót of lightness. Look at p.e. seats, battery, exhaust adding up hefty kgs. Btw JB did you delete the softtop?
Quote from: LeEdFollow on January 5, 2023, 12:04a dry/kerb weight of 950kgs which is what I read it was online.
Quote from: Petrus on January 5, 2023, 12:51Oh and about your battery. Moving it up front means adding héavy cable. Whether you want the weight from the rear to the front is questionable. The track experts are better versed in answering that.
Quote from: threepot on January 5, 2023, 14:53I've moved mine to the front, as I found with the front trunk gutted out on both cars they were a bit prone to locking up front inside wheel and occasional unexpected surprise understeer on turn in especially on Knickerbrook where there is no braking to load up the front for the turn in (note: this was pre semi slicks and camber). Thus instead on the track car I moved the battery to the front as low and central as possible, and I run a full sized normal lead acid battery. I think the front plastic undertray is important too as I went out without it and the car felt far less confidence inspiring at higher speeds, almost floaty.

Quote from: Petrus on January 5, 2023, 15:46The front under plastic is important for limiting lift. Venting the bonnet helps too. A bit of rake ditto.@JB21 extending the custom bottom shield will reduce lift more but it needs to be compensated in the bonnet because the air through the rad needs to go sómewhere.
Quote from: JB21 on January 5, 2023, 15:48ideally a tilt on the rad too to help the airflow upwards,
Quote from: LeEdFollow on January 23, 2023, 09:46So I've finished the rust removal/painting/undersealing to half way down the car Just now need to tackle the rust in the rear of the sils (which will require some welding) and then the rust in the engine bay either side of the exhaust.Fitted all my Cusco braces (Front Strut, Rear Strut and Centre Breatplate) and that's add 3kgs to the car. But I'll get that back plus more by removing the stock intake pipework and the stock exhaust system (plus heat shield)
